Question

complete the conversion.
1 foot = 12 inches
3½ feet =

inches

Explanation:

Step1: Convert mixed number to improper fraction

First, convert \( 3\frac{1}{2} \) to an improper fraction. \( 3\frac{1}{2}=\frac{3\times2 + 1}{2}=\frac{7}{2} \).

Step2: Multiply by conversion factor

Since 1 foot = 12 inches, to find the number of inches in \( 3\frac{1}{2} \) feet, multiply \( \frac{7}{2} \) by 12.
\( \frac{7}{2}\times12 = 7\times6 = 42 \).

Answer:

42
